How many lines does iPhone 13 Mini support?

I'd like to use 3 cell providers but I can't tell if my network unlocked iPhone 13 Mini supports it.

Preferably I'd like to have 3 eSIM's with 2 active in the same time. Nor my cell providers neither Apple customer serves was able to tell me how many eSIM's can I store in my phone.

Using Dual SIM with an eSIM - Apple Support says: "All iPhone models that support eSIM can have multiple eSIMs and use Dual SIM with two active SIMs at the same time." What does multiple mean? 2, 3 or more?
